SASH-LOCK.

SPECIFICATION forming part of Letters Patent No. 782,051, dated February 7, 1905.

Application filed April 4, 1904. Serial No. 201,399.

To 17/ who/1t if m/u concern.-

Be it known that I, At Liam: RAMAGE, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri. have invented new and useful Improvements in Sash-Locks, of which the following is a specification.

My invention relates to improvements in sash-locks.

The object of my invention is to provide a sash-lock by means of which a window-sash may be securely held locked in an open or a closed position and which cannot easily be released by a person outside the house.

.\ly sash-lock adapted for use on either the upper or the lower sash-frame.

)ly invention consists in two members longitudinally slidable one on the other, one member being provided with means for engaging with the window-frame and the other with means for securing to the sash-frame, one member having one or more transverse holes d isposed along its length, the other member having a resilient tongue adapted to enter said holes when the sash is properly positioned for the purpose of locking the two members together. The disposition of this tongue is such that access to it cannot be readily obtained from the outside of the window.

In the accompanyingdrawings, which illustrate my invention, Figure 1 is a front elevation view of two sash, the upper and lower ones, mounted in a window-frame and provided each with one of my sash-locks, a portion of the window-frame and of the upper sash being broken away. Fig. 2 is a longitudinal vertical sectional view of one of the locks. Fig. 3 is a perspective view of the outer member. Fig. I is a similar view of the other member, and Fig. 5 is a vertical sectional view of a modified tongue-locking device in which the inner end of the tongue is upwardly turned to prevent it being forced out of engagement with the inner strip when the sash is moved lengthwise.

Similar characters of reference indicate similar parts.

I denotes the window-frame; 2, the upper and 3 the lower sash-frame.

metal, having a concave inner and a convex outer side and provided with a plurality of transverse holes disposed along its length and adapted to receive the inner projecting end of a resilient tongue 5 on the upper end of a vertical member 6 when the same is applied to the lower sash, disposed on the outside of and slidably mounted upon the member -t. .\Ieans are provided by which one member is slidably locked to the other. In the form shown the member 6 has its side edges folded at T, so as to embrace the side edges of the member I. The upper end of the member I is provided with a lateral lip S, having a transverse hole 9 to receive a securing-screw 10, adapted to be inserted in the sash-frame 3. The lower end of the member 6 is also provided with a lateral lip 11. provided with a transverse hole 12, adapted to receive the securing-screw 13, adapted to enter the window-sill when the device is applied to the lower sash. On the outer side of the tongue is provided a projection 12k. by which the tongue is sprung outwardly, so as to remove the projection 15 at the end of the tongue from the hole 16 in which it may be disposed. The concave inner side of the inner member I provides for the entrance of the projection 15 on the end of the tongue without its striking the windowframe. 'hen applied to the upper sash, the positions of the members t and 6 are the reverse that in which they lie when attached to the lower sash. \Vhen applied to the upper sash, the lip 11 of the member 6 is secured to the upper part of the wimlow-frame and the tongue is at the lower end. The position of the member I is correspondingly'reversed, the lip 8 thereof being at the lower end of the member I. The positions, however, of the two members relative to each other are unchanged.

In the form of tongue shown in Fig. the innerendof the projection 15 isprovided with a vertical projection IT, which prevents the tongue being forced out of the hole by upward pressure on the lower sash when the device is applied to such sash.

In operating my invention the devices are applied one to the lower sash and one to the I is a vertical member, preferably of sheet 1 upper sash in the manner before described.

By drawing out the upper end of the tongue 5 on the lower sash the sash maybe moved vertically to the desired height, when the tongue is released and permitted to enter the adjacent hole 16 in the member 4. The window-sash will thus be held from vertical movement. The position of the tongue 5 is such that it is not readily accessible from the outside of the window. To lower the upper sash, the tongue 5 of the upper device is withdrawn from the hole 16 in which it is disposed, after which the upper sash is lowered to the desired position and the tongue released to enter the adjacent hole in the inner strip 4. The upper sash will thus be held locked in the said position.

In the form of tongue shown in Fig. 5 the tongue at its upper end is inwardly and then upwardly bent to form the projections 15 and 17. A lateral projection 18 is forced outwardly from the body of the tongue to provide means for withdrawing the" tongue from the holes 16.

My invention is capable of being modified in different ways without departing from its spirit.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. A sash-lock comprising two members provided one with means. for securing to the sash and the other with means for securing to the window-frame, one member being provided on its inner side with a longitudinal groove and having one or more transverse holes extending through the member and dis:

posed one above the other, the other member being mounted on the outside of the grooved member and provided with a resilient tongue adapted to enter said holes, one of the members having longitudinal guides in which the other member is slidable.

2. A sash-lock comprising two sheet-metal strips each having one concave and one convex side and one strip beingslidably mounted on the other with its concave side against the convex side of the other strip, the side edges of one strip being folded and embracing the side edges of the other strip, one strip being provided along its length with a plurality of holes extending transversely through the strip, the other striphaving a resilienttongue adapted to releasably engage the other strip through said holes, one strip being provided with means for engaging the sash-frame and the other strip having means for engaging the window-frame.

3. A sash-lock comprising two sheet-metal strips, one of which has a concave inner side adapted to lie adjacent the window-frame and having a plurality of transverse holes disposed along its length, the other strip being slidably mounted upon the outer side of the first strip and having longitudinally-folded side edges engaging the side edges of the inner strip, the outer strip having a resilient tongue adapted to enter the holes of the inner strip and provided with an outwardly-extending projection for removing said tongue from said holes, one end of one strip being provided with a laterally-extending lip for being secured to the sash, and the other strip having at one end a lateral lip for being secured to the windowframe.

4. A sash -lock comprising two members each comprising a longitudinal straight metallic strip having the form of a longitudinal section of a tube, one member having a plurality of holes arranged along its length and a lateral lip for securing to the sash-frame, the second member being similarly formed and having its side edges folded to form grooves in which the side edges of the other member are disposed, the second member having at one end a lateral lip for securing to the window-frame, and the other end having an integral resilient tongue provided with an inwardly-extending projection adapted to enter the holes in the other member, the said projection having at its inner end an upwardlyextending projection, the said tongue having a projection forced outwardly from the body for being gripped to remove the tongue from said holes.

5. A sash lock comprising two vertical members, .one provided with means for being secured at its lower end to the window-sill, the other member being provided with means for being secured at its upper end to a sash, the free ends of said members being slidably mounted side by side upon each other, one member being provided with a longitudinal series of holes, the other member having a resilienttongue for engaging said opposite member through said holes, and one member having folded portions for embracing the opposite member.

6. A sash lock comprising two vertical members, one provided at its lower end with a horizontal securing-lip for fastening to the window-sill, the upper end of said member being free, the other member having at its upper end a lip for securing to the sash, the lower end of the second member being free, the free ends of said members being slidably mounted side by side upon each other, one member having a longitudinal series of holes, and the other member a resilient tongue adapted to enter said holes, and means for securing said 'members together but permitting their sliding movement relative to each other.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
